The installation difficulty of PVC corner protectors is relatively low and can be constructed synchronously with wall decoration. The core is to do a good job in base treatment, precise positioning, and firm adhesion. The installation steps of different types of corner protectors may vary slightly, but the overall process follows the “base treatment positioning adhesion leveling finishing” to ensure that the installation is smooth, firm, and free of looseness.
General installation steps: The first step is to treat the base layer, clean the dust, oil stains, and protrusions at the corners and joints, fill in the depressions, and ensure that the base layer is flat, dry, and free of looseness. Uneven base layer can cause the corner protector to not be firmly attached and easily fall off in the later stage. The second step is to locate and lay out the lines. According to the decoration design requirements, mark the positioning lines at the corners or joints to ensure that the corner strips are installed vertically and horizontally, avoiding tilting. A level ruler can be used to assist in positioning. The third step is to paste and fix. For ordinary corner protectors, glass glue, special adhesives, or cement mortar can be used for pasting. For grid cloth composite corner protectors, cement mortar is preferred. The bonding material should be evenly applied to the back and sides of the corner protectors. The grid cloth should be attached to the wall to ensure full bonding and no hollowing.
The fourth step is to level and adjust by aligning the corner protector with the positioning line, pressing it firmly, scraping off excess bonding material, checking the verticality and flatness with a level ruler, and adjusting it in a timely manner to avoid tilting or bulging. The fifth step of finishing treatment is to dry the bonding material (cement mortar needs to be cured for more than 24 hours), apply putty to the joint between the corner protector and the wall, and press the mesh cloth into the putty to ensure a smooth and seamless connection. After drying, sand it with sandpaper, and finally apply latex paint, paste wallpaper or tiles to complete the finishing process.
Caution: Construction on rainy days is prohibited as damp base layers can affect the bonding effect; The joint of the corner protector should be aligned without misalignment, and the gap should be controlled within 1mm. It can be filled with putty for decoration; High frequency contact areas such as children’s rooms and corridors can be reinforced with additional nails or sealant after pasting; Decorative corner protectors need to be confirmed for direction and color before pasting to avoid reverse pasting; The composite corner protector strip of the mesh cloth should ensure that the mesh cloth is wrinkle free and does not fall off, enhancing the adhesion with the wall.
